DISK-FEEDING MACHINE.

Specication of Letters Patent.

Patented oct. 2o, 1914.

To all whom it may concern Be it known that I, OSCAR J OLM, ofMlnncapolis, Hennepin county, Mlnnesota, have invented certain new and useful Improvements in Disk-Feeding Machines, of which the following is a specication.

My invention relates to machines for fastening washer-like disks t o the body or flap of an envelop or other article:l

The object of my present' invention 1s to provide" improvedy means for feechng areinforcing disk or section, preferably 1n tape form. to an eyelet upsetting anvil and pin, preparatory to securing the relnforclng section to the envelop or other artlcle. Generallythese reinforcing sections, placed on `the inner face of the envelop body and the.

flap,A are fed by hand t0 the machine and my invention contemplates a much more rapid and elective delivery lof the'remforcing sections to the surface to be reinforced.

A further object is to vprovlde improved means for punching a hole in the flap to -receive.y vthe disk and eyelet.

Other objects of the inventionwill appear from the following detailed desc-riptlon.v

The invention consists generally invarious constructions and combinations, all `as hereinafter described and particularly pointed out in the claims.

ln'the accompanying drawmgs forming part of this specification, Figure 1 is av side elevation of the upper portlon of'the machine embodying my invention, showing the envelop in position for attaching the'mner and outer'disks thereto, Fig. 2 Iisa slmllar view. showing the mechanism in the act of cuttingolla disk from the strip or ribbon, Fig. 3 is a view. vpartially in section, showing thev disk feeding mechanism and the means for forming the hole in the flap at any pointy therein, F ig.- 1 is a. plan View of thev tape Or ribbon carrler, Fig. 5 1s a. longitudinal=sectional view of the same, Flg. 6 is a detail view of thetape feedingrolls, Fig. 7 is a detail view of the clutch mechani'sm for operating the rolls, Fig. 8 is -av detail sectional view ofthe means for securing uniform movement of the rolls and a corresponding feed of the tape. Fig. 9 is a detail view showing the device for operating the leverwhich disengages the tape carrier from the punching pin or die, Fig. 10 is a vie'w of the envelop showingthe disks or `washers secured to the body port-ion thereof, and the hole punched in the flap, Fig. 1 1 illustrates the completed envelop with the lstrinoh thereon for securing the flap in its close vposition, Fig. 12 shows a modified construction.

In the drawing, i2 represents the frame of the machine having a bracket 3 thereon supporting a reciprocating plunger 4. is a. lever pivoted at 6 on said bracket and having an antifriction bearing on an arm T which engages the upper end of the plunger to depress it against the tension of the springs S. A treadle bar 9 is pivotally connected with the lever 5 and extends downwardly to an operating treadle, not shown.

10 representsalhorn, having an anvil 11 formed thereon provided with a perforating pin 12 located in the path ofthe plunger.

13 represents a device 'by means of which eyelets are fed to the plunger in the usual wav, but as this eyeletfeeding mechanism forms no part of in v presentinvent-ion Ido notillustra'te or describe it in detail herein( 14' represents a tape carrier, pivoted preferably at 15 on the horn 10 and adapted to receive and guide the tape 16 from a reel 17. The carrier preferably has a top or cover 18 lprovided with slots or openings 19 through which the tape is -vicible,and also has a hole 20 adapted to register with a corresponding hole 21 in a die block 21 secured to t-he bottom of the carrier. The Hoor of the carrier preferably has an opening :22 therein and a feed roll 23 having a. roughened surface is mounted beneath said opening and yieldingly held toward a? corresponding roll 2l above'said opening bymeans of a spring 25. These'rolls'operate to feed the tape through the carrier, the upper roll engaging the surface of the carrier through an opening in the cover. -Therolls are secured preferably on shafts 26I and 2", the shaft Q7 extending l outwardly beyond the carrier and provided with a. clutch device com sed of members QS'and 29, the former being secured to the shaft*v 2T and provided with peripheral ratchet teeth which are engaged b v dogs 30 on the member 29. The dogs 30 are held in engagement with the ratchet 'teeth by springs 30 and springs 31 and 31 engage respectively the ratchet teeth and a notch fim) ' 32` in the periphery of the disk 29. These The feed of the tape is made uniform by means of adisk on the 4roll 24 and having peripheral notches 3,6 therein to receive a tooth 37 on apivoted arm 38 which is yieldingly held in engagement with the disk by a spring 39. The notches are preferably V- shaped, so that the tooth 37 will center it self automatically in its notch and insure a uniform feeding of the tape 'with each movement of the feeding mechanism.

The carrier is arrange-d to oseillate ver- 'tically on its pivots to punch holes in the tape at regular intervals and I may eeet this punching operation by the mechanism which I will now describe in detail.

40is a link, pivotally connecting the arm 31 with the long arm of a bell crank 41 which is pivoted at 42 on the machine fra me. The short arm of said bell crank has an antifriction roller 43 mounted thereon in the path of a beveled shoulder 44 provided on a vertically sliding bar 45 which is pivotally' connected at its upper end with a lever 5,(see Fig. l) so that on the upstroke of the lever 5 the bar 45 will be raised to move the beveled shoulder 44 into engagement with the anti-friction roller 43 and rock the bell crank 41 and the. arm 31 to feed the tape. The upward movement of `the carrier is against the tension ofa spring 46. A pin 47 is mounted on the bracket 3 and is adapted to register with the hole 21 when the carrier is raised and perfrate the tape above the hole 21, a guide 48 operating to prevent lateral movement of the carrier during the punching operation. In its depressed position the carrier rests upon a pin 49 and a catch 50 is preferably provided to engage the end of the carrier and lock .it in its depressed position. A spring 51 is connected with the bell crank 41 and tends to retract the bell crank and the ro'll operating arm connected therewith to the position shown in Fig. 2. The bar 45 is provided with an anti-friction roller 52 which engages the underside of the carrier and positively raises it to the limit of its upward movement against the tension of the spring 46. (See Fig. 1).

The cover 18 at the receiving end of the carrier is preferably turned upwardly, as

indicated in Fig. 5, to form an inclined bearingpsurfaee 53 and a bell crank 54 pivoted on the vbracket 3 has one arm adapted to bear on said surface and its other arm projecting into the path of a spring pressed hook 55 mounted on the longitudinal edge of the bar 45. A spring 56 normally holds the short arm of the bell crankl54 against a pin 57. The punching pin 47 sticks in the hole 21 after punching the hole in the tape suflfciently to resist the tension of the spring 46, but as the bell crank 54 is positively actuated bythe upward movement of hook 55 and bears on the inclined surface 53, it

'will' force the carrier downward and insure its disengagement from the punching pin.

The carrier is preferably provided near its pivoted end with a cutting edge 58 which is adapted to cooperate with a similar edge on the anvil 11 to sever the tape between the perforations therein, the severed section forming a disk or washer on the inner surface of the envelop, being held on the anvil and the pin 12 by suitable spring devices 59.

To perforate the body portion of the envelop, the Hap is opened and the envelop 'placed on the horn of the machine, as indicated in Fig. 1, there being a washer or disk on the anvil beneath the wall of the envelop. The attendant will then place a perforated disk over the pin 12 and the operation of the plunger 4 will-insert an eyelet point over the pin 12 and upset the ends of the eyelets to secure A'the disks to the paper, the outer disk forming a holding means for the cord while the disk on .the underside of the envelop acts as a reinforcement to the paper, preventing the eyelet from being pulled through the paper.

On the underside of the horn I prefer to provide a plate 60 having a series of holes 61 therein adapted to receive a punching pin 62 which is fitted into any one of a series of holes 63 provided in a lever 64 pivoted at 65 on the machine frame. The lever 64 is normally held in therposition shown in Fig. 3 by means of a spring 66 and one end of said lever is in the path of the lower end of the bar 45. The downward movement of the bar 45 will rock the lever 64 and move the pin 62 upwardly into one of the holes 61 in the plate 60. When the envelop is placed on the horn the flaps 684 will extend in under the plate 60 and the upward movement of the pin 62 will perforate this Hap, the position of the perforations depending upon the adjustment of the pin in the lever 64, a sufiicient number of holes being provided in said lever to allow the perforation at any suitable point in the flap and adapt the machine for perforating flaps of envelops `of different sizes.

To insure the separation of the lever 64 from the envelop flap I prefer to provide guides 69 secured to the side of the machine and projeetin outwardly upon each side of the lever 64. glhe envelop Hap is inserted between these guides and the plate 60. andthe guides prevent the flap from following the pin and lever when they are drawn tothe position indicated in Fig; 3. After-the perforationhas been made in theI flap and the disks secured to the body of the envelop,

the operator willxemove the envelop fromthe horn, turn it over and secure a.4 re-inforeing disk to the inner face of the flap and the outer disk. or. washer to the outer face of the flap in the same manner as thedisks are secured to the body of the envelop. The string is then attached and the envelop is ready for use.

In Fig. 19 I have shown a modification which consists in providing a perforation in the upper wall of the carrier, forming a die to receive a punch 71 mounted on .the horn 10 and adapted to register-with the hole 70 to perforate the tape as it is fed between the upper and lower walls of the earf rier. This perforation will take place when the carrier is tilted and its pivoted end is lowered, so that the punch will Contact with the tape and at the same time the severing knife 59 will cut the tape between the perfo. rations. This construction I may prefer to employ in the machine, as it is simple and easily applied Aand may be more accurate than the punching device described with reference to the previous figures.

In the operation of the machine, the ttipe will be fed toward the upsetting anvil and pin by the mechanism which operates the plunger, but as the forward end ofthe tape approaches the pin it will be tilted to direct the pin into engagement with the perforation in the tape, the perforation having been previously formed by the tilting of the carrier. When the eyeletupsetting pin has engaged the hole in the tape the carrier will be tilted to brin the tape into engagement with the punti to perforate another hole, and at. the same time theseveringknife Will become effective to cutthe tapel between the perforations, and during the time that the tape is being severed and punched, the severed section will be held down on the anvil b v the yielding means described until t-he descent of the. plunger secures it to the surface to be reinforced.'

I do not wish to be confined in this application to the mechanism shown and described for operating the various parts ofthe machine, as obviously these features may be changed in man v ways and still -be within the scope of my invention.
